Abstract: The challenge that arises by the arrival of cloud computing is to carefully control the data that are no longer in possession of the company alone, but may be in the hands of third parties (TTP). Managing user trust is a major concern related to the management of migrated data in a Cloud. Dealing with this issue, our paper contributes to this process by defining a security policy based on trust, followed by the description of a security protocol for a TTP monitor attempts to violations of this policy by users of an organization’s cloud. This protocol is based on ordered policies established by the AS and assigned to each user during its connections to the cloud.
